Standard Bank robbing me my money

I had an existing cheque account with the bank and which has not been used for over a year now and is on a negative, i recently got a AF claim paid into the account and since it was owing the money got deducted and i am left on a minus still. I called standard bank to make the funds available and make an arrangement of the outstanding amount to be paid monthly they refused which is fine. Then i asked them to close the account then so that it stops charging all the interest and will be owing only what is left and was told by Sihle in collections Standard Bank wont stop or close the account it will continue accumulate interest... Mind you when i called last week initially would account is dormant, then when calling today got hold of Unity who didn't want to listen but transferred me to collections then i got hold of Thato who sent me back to enquires and another lady sent be back to collections and i spoke to Sihle.
